[Not a Bug][Bug 1.04] roof station not working

after researching body specialization i tried to set up stations for body assembly and then roof assembly but the cars will not enter the roof station. they stop in front of it. ive tried replace the convayer a few times to make sure it was right and even deleted the roof assembly station and built another and it still wont work

are you sure you have everything in the right order? do the cars look like they have the body already installed and are just waiting for the roof and doors?

im pretty sure. i have a fit bodyframe station(bottom right of pic) then a fit roof station(top left).

nevermind it seems to be working i need to have the door assembly connected to get it to work. i must have messed up the convyer to the door assembly the first time and not noticed
